Started using mineral makeup last summer-- Smokey Mountain Minerals (from Ebay http://stores.ebay.com/Smoky-Mountain-Minerals). Very pleased with the results. It was inexpensive, considering how long it lasts, too. Haven't tried the 'name' brands.
My skin is combination dry/regular--that may make a difference in the staying power. My skin looks good. feels good. Really lasts for me, on the job, around a campfire :) and in over 100 deg desert weather too.
fwiw-- I'm a reenactor (Victorian period) and wanted something that looked good...without using modern day makeup. I've been able to accomplish that, without breaking any reenactor 'no makeup' dress code.
Learning to apply the concealer and foundation powder took a few extra minutes, the first time I washed it off and started over :) Btw, where needing concealer I pat it on with the tip of my little finger (first step). Follow with foundation using a professional powder brush and 'daub' the powder on. Plus blush color. Let it set while 'doing' my eyelashes, then dust off any extra. I don't always use the 'finishing' powder. Two very light coats are better than one thick application. Touch ups don't show, either!
HTH, experiment with a starter kit perhaps...
